[0001] The invention relates to a technical field of electrical connector, and more particularly to an electrical connector configured to mate with a plug of RJ45 connected to a cable.Description of the Related Art

[0002] Conventional RJ (Registered Jack) electrical connectors mainly include two kinds, the RJ11 connectors and the RJ45 connectors. The RJ45 connectors have a size greater than that of the RJ11 connectors, and each of the RJ45 connectors has eight terminals for requirements in computer network and digital communication.

[0003] As the technology of communication develops, demands for the data transmission speed and the bandwidth for communication are continuously increased, for example the data transmission speed is increased from 155 Mbps to 1 Gbps, 2.5 Gbps or even 10 Gbps, However, the higher data transmission speed the conventional RJ45 connectors provide, more electromagnetic waves are generated by the eight contact terminals, whereby the signals transmitted in the eight terminals are interfered by the electromagnetic waves.

[0004] Moreover, the conventional RJ45 connectors have eight terminals arranged in a separated manner, i.e. not in the same axis, which causes a more complicated soldering process for the connectors.

[0005] Therefore, it is an important issue for the conventional RJ45 connectors to reduce electromagnetic interference and simplify the soldering process.BRIEF SUMMARY OF THE INVENTION
